THE
CONCEPT:
Immunosenescence
Immunosenescence is an insidious process which leads to:
Ø
Ø
Impaired responses to antigen exposure
Ø
Ø
Increased infectious disease morbidity & mortality
Ø
Ø
Increased incidence of Cancers, Vascular Diseases, and Autoimmune
Disorders
Immunosenescence
Current research shows that,
like the brain, the Immune System can become senile. This is known as “Immunosenescence”, the condition of decline in immune function as
you grow older. Quite surprisingly, this decline typically begins early on in life, and then worsens as we advance in
age.
THE
PHENOMENON: Immunosenescence
Immunosenescence also involves the inflammatory changes which can be important determinative factors in the
chronic diseases and general frailty associated with Aging including:
Ø
Ø
Advanced Cancers & Metastases
Ø
Ø
Coronary Heart Disease and Heart Attacks
Ø
Ø
Cerebrovascular Disease and Strokes
Ø
Ø
Alzheimer's Disease (Presenile Dementia)
Ø
Ø
Inflammatory Bowel Disease and Crohn’s Disease
Ø
Ø
Metabolic Syndrome and Diabetes
Ø
Ø
Osteoarthritis and Osteoporosis
Ø
Ø
Rheumatoid Arthritis
Immunosenescence is primarily
characterized by a gradual depression of cellular functions throughout the immune system. It has been shown scientifically to be directly
associated with a phenomenon called “telomere shortening”, which weakens our ability to produce the new immune cells needed to protect the
body from disease. Immunosenescence can also provoke the development of autoimmune disorders.
Natural killer (NK) Cells
The cells most severely
affected are Natural Killer (NK) cells, the body’s first line of defense against Cancer, microbial infections, and many other serious
diseases. Many scientific studies also show a link between NK cell deficiency and autoimmune diseases, susceptibility to Lyme Disease,
and Chronic Fatigue Immune Dysfunction Syndrome (CFID). People with NK cell deficiency also show increased susceptibility to
phases of Herpes virus and influenza virus infection and recurrence.
Cancer
The current scientific evidence
clearly indicates that advancing age is the single greatest risk factor for the development of Cancer. Specifically, the incidence of
Cancer increases in advanced adults who demonstrate age-dependent progressive immunosenescence and its resultant NK cell
deficiency.
Natural killer (NK) cells are specifically known to kill invasive tumor cells. They accomplish his by
binding themselves to cancer cell membranes and injecting powerful enzyme granules which cause the cancer cell to dissolve in death within five
minutes.

Infectious Diseases
Immunosenescence is an insidious process which weakens human
immunity against exposure to viruses (e.g., Influenza), bacteria (e.g., E. coli) and other infectious microbes. Among other factors, it
is the NK cell deficiency which leads to an increased in the severity of illness and death rate from infectious diseases.
Coronary Heart Disease
Viral and bacterial infections are now recognized as major risk factors for Coronary Heart Disease (CHD).
As the first line of defense against those infections, a weakened and depleted NK cells may open the door to the development of
CHD
